    材料四:印度提倡“只生一個(gè)好”——鼓勵(lì)三人小家庭 生男生女都一樣材料五:印度尼西亞《人口發(fā)展與幸福家庭法》材料六:我國基本國策 計(jì)劃生育(小結(jié))通過對(duì)以上材料的分析我們可以得出這樣的結(jié)論,不同的國家應(yīng)該采取不同的人口政策,對(duì)與發(fā)達(dá)國家來說人口增長緩慢,應(yīng)采取鼓勵(lì)生育,吸引移民的措施;發(fā)展中國家人口增長較快,實(shí)行控制人口的政策已經(jīng)迫在眉睫。不論是發(fā)達(dá)國家還是發(fā)展中國家共同的目標(biāo)就是實(shí)現(xiàn)環(huán)境人口和社會(huì)經(jīng)濟(jì)的協(xié)調(diào)發(fā)展?!菊n堂小結(jié)】這節(jié)課我們主要學(xué)習(xí)了人口的自然增長,影響人口自然增長的因素有哪些?(人口的自然增長率和人口的基數(shù))世界人口的數(shù)量在不同的歷史時(shí)期表現(xiàn)出不同的特征,同一歷史時(shí)期的不同地區(qū),人口數(shù)量的增長又有不同的特點(diǎn)。面對(duì)不同的人口形勢(shì),各國應(yīng)采取不同的人口政策。

    1.促使美國成為一個(gè)移民國家的因素是:①美洲屬于未開發(fā)的新大陸,需要大量的勞動(dòng)力;②歐洲失業(yè)工人和破產(chǎn)農(nóng)民增加,人們?yōu)榱俗非蟾玫慕?jīng)濟(jì)待遇遷往美洲;③新航線的開辟為人們順利遷移掃除了障礙;④殖民擴(kuò)張是人口遷移的促進(jìn)因素,加快了人口遷移的過程。導(dǎo)致美國人口在本土范圍內(nèi)頻繁遷移的原因,歸納起來有:第一次人口遷移是戰(zhàn)爭因素,第二次是城市化;第三次是自然環(huán)境、經(jīng)濟(jì)環(huán)境的變化;第四次是經(jīng)濟(jì)格局的變化,即西部和南部新資源的發(fā)現(xiàn)和新興工業(yè)的發(fā)展。2.我國古代的人口遷移,深受統(tǒng)治者及其行政力量的束縛。封建帝王為了加強(qiáng)本國的經(jīng)濟(jì)和軍事實(shí)力,對(duì)人口遷移嚴(yán)加控制。只有當(dāng)戰(zhàn)亂發(fā)生的時(shí)候,這種控制才得到削弱,人們?yōu)榱硕惚軕?zhàn)亂,尋找安定的生活環(huán)境,不得不進(jìn)行大規(guī)模的遷移。我國近幾十年的人口遷移主要是由生產(chǎn)資料和勞動(dòng)力數(shù)量上的地區(qū)分布不平衡造成的,是經(jīng)濟(jì)因素在起主導(dǎo)作用,與古代的人口遷移截然不同。

    1.澳大利亞混合農(nóng)業(yè)地域在生產(chǎn)結(jié)構(gòu)、經(jīng)營方式、科技應(yīng)用、農(nóng)業(yè)專業(yè)化和地域化等方面有哪些特點(diǎn)?2.在澳大利亞混合農(nóng)業(yè)地 域形成的過程中,有哪些區(qū)位因素在起作用?學(xué)生發(fā)言,教師適當(dāng)引導(dǎo)、評(píng)點(diǎn)并作講解。[教師提問]:那么,澳大利亞的墨累—達(dá)令盆地的區(qū)位因素有什么不足之處?知識(shí)拓展:課件展示澳大利亞大分水嶺的雨影效應(yīng)的形成原理及東水西調(diào)示意圖。[教師講解]:澳大利亞東南部受大分水嶺的影響,降水集中于大分水嶺的東側(cè),在其西側(cè)形成山地的雨影效應(yīng),降水豐富地區(qū)與農(nóng)業(yè)生產(chǎn)地區(qū)分布不一致,灌溉成為澳大利亞農(nóng)牧業(yè)發(fā)展的限制性條件。因此,澳大利亞對(duì)水利工程建設(shè)很 重視,東水西調(diào)促進(jìn)了墨累—達(dá)令盆地農(nóng)牧業(yè)的發(fā)展。[課堂小結(jié)]:這節(jié)課我們學(xué)習(xí)了農(nóng)業(yè)區(qū)位選擇的基本原理。 通過學(xué)習(xí)我們了解到,農(nóng)業(yè)的區(qū)位選擇實(shí)質(zhì)上就是對(duì)農(nóng)業(yè)土地的合理利用。
